1928. Serial This invention relates to Water heaters and in particular the base and burner assembly therefor. j

This application is a division of copendi-ng application, Serial No. 123,690, which has maturedinto. Patent 1,759,891, filed July 20, 1926, by Watler W. Ziegler,'Loran F Dosh and Edmund J. Te Pas as joint inventors.

It is customary in water heaters of the usual type, in which a tank of water is heated by the flame from a gas burner positioned below water circulation elements in communication with the tank, to mountjthe burner upon the Bunsen or mixing tube by either a ground or a threaded joint. 1

When a ground joint is used the end of the Bunsen tube is finished smooth and slightly tapered and adapted to snugly fit into a bored out cylindrical extension of the burnerQ This arrangement of parts is open to theobjection that uponremoval and replacement of the burner a gas-tight fit may not be achievedon account of dirt or other foreign material lodgingbetween the contacting portions of the Bunsen tube and burner.

'Inorder to overcome this objection and still 'etain advantages of the. ground joint, such is ease in removal'and replacementof the burner for cleaning etc., heaters have been made in which the Bunsen. tube and burner are provided with a threaded j ointto insure at all times a gas-tightconnection at this point." Experience has shown'that after a time the threaded joint becomes rusted and it is impossible to remove the burner from the Bunsen tube without the use of tools which'cannot be manipulated in the limited space in the heater casing. In this case the heater base which carries the Bunsen tube and burner is removed from its casing andthe burner is then removed from the 'Bun'sen'tube, n

One of the objects of this inventionis to provide a heater base in which the assembled burner and'Bunsentube can be quickly; and easily installed or removed without disturbing the attachment of the baseto the heater casing. r t

Another objectfof this invention is to provide an improvedmean sofconnecting the Bunsen tube to the gas feed line. These and other objects will appear from the following detailed description and appended claims. 1 In the accompanying drawings forming a part of this specification are illustratedembodiments of the features of this invention in which: Fig. 1 is a side elevational view partly in section of a Water heater with a section ofits base removed and embodying features of this invention. Fig. 2 is a. sideelevational view of the Bunsen or mixing tube. Fig. is a perspective view of the heater base member used in Fig. 1. I 1 Referring to Fig; 1, the numeral 1, desighates the casing of a heater having a heating coil 2 adapted to be connected at itsextremities in the usual manner to the top and bot tom of a boiler, so that there is a circulation of water through the coil and boiler when the burner is in operation. mounted'on a Bunsen or mixing tube 4 by means of a threaded joint.

Means comprising projecting lugs5 and a collar 6 forming. an integral part ofthe Bunsentube cooperate with helical projections or ledges 7 in a. central aperture 9 of the base 8 to securely and detachably hold the Bu'nsenvtubein position in the heater base. A pair of diametrically opposed vertical slots 10 are provided for reception of the lugs 5 and to permit'the insertion and removal of the Bunsentube in the assembled heater base; The heater base 8 is made in two pieces com-' prising the fixed element 11 and the removable element-12'shown in Fig. 3, and theyare provided with skirted portions 13 and a recessed portion at 14 to form a dripcollection and evaporation pan forthe collection of condensate from the heatingcoils. A raised seat 15 having positioninglugs lfi is adapted mit the insertion or removal of the burner and'Bunsen tube intheir: assembled state, the removable segment 12 fits in a vertically Walled space of a similar outline 1n the base The burner 3 is ber 11, to positioniandi'supporbthesection li At the central. apertures'9thecontactlng.

portions of the fixed and removable elements 11 and 12 are cut on an angle from lbw-V91 tical as at 27 and 28 to further assist in prop;

erly locating the removableelement'12; and

to permit the fixed element 11 to wholly'support the-Bunsen tubewhen in its lockedposition. asshown inllig, 1. It iszapparent'from the. foregoing. descriptiontaken in connection with a Figure. 3,; that the. removable section l2.an d.theassembledlburner head and mixing-"tube. can be. easily and readilyqre movedand replacednvithoutthe use of'any tools.

As afurther, means of facilitating. thezremoval.and freplacement of theburner assems bljga combined: union and spud holder 31 is screwed. into the. lower. endlofthe Bunsen tube 4. The lower end OftlllSzllIllOIL carries agasxcock29 tocontrol the :flow of gas: from a inain fuel a feed... line tothe burner. The male. element of the. union 31 isv held from turning. in the BunSQl ...tube by. a, locknut 3,3 Whichalso serves to loclpthev air shutter. 3 lin position. The union. nut 32.. serves. to. hold the-uniontogether, and upon loosening-it the Bunsen tube. may be. readily. disconnected from the gas line, permitting the removalLof the. Bunsen tube with its. associated. burner from theheater base :inthe manner described.

Furthermoreit is to be understood. that the particular forms of apparatus :shown and described, and. the particular procedure. set forth, are presented for purposes. of. ex;- planation and illustration. and that; the vari ous. modifications of said apparatus andprocedure can bemadewithout; departing from myinvention asdefined in the appended claims.
